The app will let Smart TVs tune into 138 broadcast channels as well as video on-demand provided by LG U+.

A Samsung IPTV app that would allow U.S. consumers use their HDTVs to watch cable or satellite without a set-top box has not been available yet, although the S.

Samsung said it would also roll out IPTV access with Estonian provider Elion.
